Be it known that I, EDWARD F. KUNATH, citizenof the United States, residing in J er- .sey City, in lthe county of Hudson and Statey of New Jersey, have 'invented certain'new` and useul Improvements in Type-Writing Machines, of which the following is aspecication.

This invention. relates to tabulators for tpye-writing and othermachines, and is adapted' particularly to machines in which' the types strike upon the front side of the platen, so that the4 operator may see the `writing as it progresses.

The invention relates to means whereby the operator may select and operate any particularV one ofv a seriesA of column-stops, and thereby cause the release of the carriage and its arrest by the selected stop. The columns written upon the paper being in constant view, the operatorcan refer constantly thereto and readily determine whether to skip one or 'more lcolumn-stops, the latter being mounted for this purpose at the front of the machine above the keyboard. In carrying out my invention I'mount a series of column-'stops at. the front ol" the machine, preferably upon the framework, and I also mount upon the carriage a coperating stop. Instead of the latter there may in some cases be used a series of denominational stops. f All ofthe column-stops are normally out of use and so mounted that by pressing upon any stop it may be lmoved into effective position. I also provide mechanism which v is movable by means of pressure upon any selected celu Inn-stop for releasing the carriage from the control of its letter-feeding mechanism. Thus bya simple pressure upon any selected stop the same is put into working posi-tion, and the carriage is released and caused to run down until arrested by the engagement ofitslstop with the operated columnstop. The column-stops I mount upon a bar, so that any one ofthem may be turned upon thebar, and by a further movement both the stop and the barl are carried backard until the stop enters the path ofthe carriage-stop. Said movement of the bar effects the release oi the carriage; I also' provide means wheref' by said vcolumn-stops.may all 'be turned simultaneously into `auch position and `there .held by mechanical means that it4 will be necessary only to move the bar to and 'fro in4 l order to bring the column-stopssuccessively into play without skipping, and I connect said bar to a key at the keyboard, so that the stops thereon may be brought into use one after another when desired lby depressing said key in the usual manner. I also mount the stop upon the carriage. in such a manner that. any of the`\`column-stops may serve to arrest the carriage upon the return movement thereof, if desired. YHence if'any column-stop is set at a selected point upon the scale it can serve to arrest .the carriage at said point in whichever direction the carnage is moving. I also preferably employ said carriage-stop as an index to cooperate with the usual front scale upon the framework.

In the accompanying drawings, Figure 1 is a sectional side elevation of the well-known Underwood front-strike type-writing machine with my improvements applied thereto. Fig. 2 is a front elevation. Fig. 3 is a detail illustrating the lmanner of turning the col'- umn-stop bar soas to set all of the stops simultaneously to effective position. Figa 4 is a plan showing the normal position of the stop which is providedupon the carriage.

Against the front of the usual platen l strike type-bars 2, which are actuated the usual manner by key-operated levers 3. The platen is j ournaled upon a frame 4, which is mounted upon a carriage 5, connected by a strap to a spring-barrel 7. The carriage has a rack 8 to mesh with a pinion 9, the latter connected to an escapement-wlleel 10, which is controlled by the usual feed-dogs. (Not shown.)

At the front of the machine I mount a cylindrical ybar 11, carrying a series of column-stops .12. .Said bar extends between and is `mounted upon a pair of upstanding rock-arms 13 and 14, `hinged at 15 uponthe may swing backwardly and forwardly between the full-line and dotted-line positions connected. by abar 16, which overlies the bar 1I. i

Each of' the column-sto s is adjustable along the bar' I11 and may )e provided with an index '17 to cooperate with a scale 18,- {ixed upon the top bevel-'face of bar 16.v The column-stops are provided with teeth 19 to engage a rack 20, formed upon the under surface ofbar 16. When the teeth 19 are frameworko'l3 the machine, so that the bar` at Fig. v1. -Saidarms 13 and 14 are rigidly ICO f one key stands higher than the other.

out of the rack, as at A, said stop may be adjusted along the bar 11 and then turned upon the bar to rengage the'teeth, as at B.v The stops are held in the latter position by means of small balls or plungers 21, provided in the recesses 22 in the bodies of` the stops -and key is mounted at the base thereof, sothat The column-stops having Vbeen adjusted pressed back by pressure upon the key 26 the front face of bar 16. By this movement spring 23 is compressed as the ball 21 rides z 5 up the rear incline of the groove 24. Continued pressure effects a backwardmoveinto the path of a stop 27, provided upon the carriage. During said movement of the bar ,o 11 the arms 13 and 14 rock backwardly. Arm

i pressed and by means of a link 29 forces down a lever 30, which has a roller-stud 31 to an arm 33, the latter depending froml a rockv shaft 34 at the rear end of the'machine, so that by movement of bar 11 said shaft .34 is rocked. Upon the latter is also provided an roller 37 to engage thejunder side of the rack 7 and lift the latter from the pinion 9', Whereby 4the carriage is freed from the control of the mechanism and rapidly advanced by the spring-barrel 7V until the st op` 27 engages the A bar 38, mounted by arms 39 upon said rock-shaft 3.4-, is also brought into engagecarriage to prevent unduly ra id movement 4of the latter. from'pressure the parts are4 returned to normal ost'ion by means of a 'spring 41 beneath thelldver 30, the rack 8 droppin by itsown Weight or otherwise. The bal 21, being pressed by spring23 against the rear inclined wall of groove 2.4, serves to return the stop 12 Vto positlon B.

It willl be understood that the .actuated ycolumn-sto which is shown at theposition C in dotte 'lines in Fig.y 1, is the only sto with whichwill engagefthe stop= 27, since al they are not in t e path o .said stop 27; and are hence ineffective. a

pressed by springs 23 into a groove 24,exv

C relatively along the bar, any selected stop may be' `until the index 17 is arrested by contact with.

ment ofthe bar until. the stop 12 is brought 28, extending rearwardly from arm 14, is de engage a cam 32, formed in the loweren'd ofA arm 35, that depresses the rear end of alever f 36'tlhe latter carrying upon its forward end a projected `stop 12 and arrests the carriage. l.

the right after en ment with a leather strip 40, fixed upon: the' Upon Vthe relie of the key 26' of the other sto vs are in osition'B, where i It will be seen that normally all of the stops are out of effective position; but if lit is desiredi to put them all into effective osition it is only necessary toturn the sha t 11, which for this purpose is mounted to rotate in bearings in the arms 13 and 14. This turning movement may be effected -byl a fingerpiece 42, .the stem 43 whereof is fixed in the end ofthe bar 11 and adapted to engage either of a pair of notches 44 45, thel former movement bringing all the stopsinto ineffective position B, while the latter move` ment brings them'all into effective position to bar'll. In the last case a key 46 provided upon the endof the lever 30, 48o may be depressed in order 'to operatethe describedtabulating mechanism. Hence said -fkey 46 may be employed in the usual manner for tabulating, in which the work proceeds without a break, while when there are many skips to be made the stem 45 may be swung to the full-line position at Fig. 3 andthe keys 26. used as required instead ofthe key 46.

'The stop 27 also serves as an index to cooperate with a front scale 47, provided', as 9o usual, upon the Jframework of the machine- Said stop 27 is also adaptedto arrest the return movement of the carriage by coperation with the column-stops 12. The stop 27 consistsof a spring-arm, which is pivoted at 48V upon the lcarriage and vibrates to a limited extent betweentwo abutments 4,9l and '50, also provided upon the carriage.-

spring 51- holds the stop-arm 27 normally' c against thel 'abutment 49, the stop 27 not vi" roo brating during the usual tabulating operations heretofore described. When, however,

it isv desired to arrest the carriage 'at a predetermined point upon its return movement, a column-stop 'is set to said point by means of, 105 index 17 and scale 18, and said colunm-stop is pressedbackward in the manner already` described and the carriage moved manually `to the right until arm 27 engages with the pro' jectedstop- 1,2. The pivoting ofv the latter .,IIo enables it to yield, so that the carriagemay continue to .move a shortextra distance to I agement of 27 .12, this extra vmovement eing limitedby the abutment 50. This extra or4 lost motion of the 1 15 carriage-compensates for the thickness of the stop. In other Words, the carriage goes backto such a point lthat When' released it will come to rest at a point agreeing with theA point uponthe-scale 18 to which the part'v17 .12o
